The attack on the town of Gimbi was connected to fighting between government forces and the OLA, according to a statement from the Ethiopian Human Rights Commission (EHRC).
The EHRC told CNN Monday that the assault has left “scores of people injured, villages destroyed, and entire communities traumatized.”
The OLA — which last year aligned with Tigrayan rebel forces against Ethiopia’s federal government in the country’s protracted conflict — has denied all the allegations. OLA spokesman Odaa Tarbii said Sunday that the “regime” of Ethiopia’s Prime Minister Abiy Ahmed “is again blaming the OLA for atrocities committed by its own retreating fighters.”
The rebel group has been designated as a terror organization by the Ethiopian government, and it is frequently accused of attacking civilians and targeting ethnic Amharas.
This incident is among the worst atrocities to hit the country since fighting broke out in Ethiopia’s northern Tigray region in 2020, when Abiy’s government and its allies from the neighboring Amhara region tried to suppress a rebellion by the Tigray People’s Liberation Front (TPLF).
The TPLF dominated Ethiopia’s government prior to Abiy’s rise to power in 2018.
The ensuing civil war has seen both sides carry out atrocities, according to human rights groups, and risks splitting the ethnically diverse country. There is no suggestion TPLF was involved in Saturday’s attack.
A local police officer involved in the response effort to Saturday’s incident told CNN that an attack happened near Tole, a village within Gimbi, on Saturday, with the majority of the victims belonging to the Amhara ethnic group. The police officer spoke on the condition of anonymity as he was not authorized to speak on the matter.
The assault came days after heavy fighting between government security forces and the OLA in the area, he said.
Survivors and escapees told the police officer that the attack started when members of the OLA attempted to cross through the village but were denied passage by local residents and some armed civilians.
A resident of Tole, who only spoke on the condition of anonymity for fear of reprisal, said he saw OLA militiamen walking down a main road on Saturday morning before dispersing towards neighboring villages. Government forces, who were seen in Tole earlier in the week, had left the area days before the attack, he added.
The police officer said responders were sent to the scene on Sunday to retrieve and bury bodies.
Federal forces have now secured the area, he added, but “residents are still asking for immediate assistance due to security concerns in the area,” the EHRC said.
The Oromia regional government also accused the OLA of attacking civilians after “being incapable of resisting attacks from security forces,” and has vowed to intensify attacks on the group, according to a statement published on Sunday.
Prime Minister Abiy said the “attacks on innocent civilians & destruction of livelihoods by illegal and irregular forces is unacceptable,” in a tweet on Monday.
The head of the EHRC, Daniel Bekele, urged authorities to “ensure necessary measures for protection of civilians,” and “find a lasting solution to the problem,” in a statement from the commission on Sunday.
Ethiopia is an ethnically and religiously diverse nation of about 110 million people who speak numerous different languages. Its two largest ethnic groups, the Oromo and Amhara, make up more than 60% of the population. The Tigrayans, the third largest, are around 7%.
Last week, Abiy said the Ethiopian government has formed a committee to negotiate with forces from the Tigray region. The development marks a significant step towards peace negotiations between the two sides.
